### 4. Functionality

Operating Principle
The PCI‑8144 generates high‑frequency pulse trains to command stepper or servo drivers configured in pulse‑input mode. Each axis outputs CW (clockwise) and CCW (counter‑clockwise) signals or OUT/DIR signals depending on configuration. The pulse frequency determines motor speed, while pulse count defines displacement.

Motion Modes
- Velocity Mode: Continuous motion at specified speed until stopped.
- Position Mode: Relative positioning by defined pulse count.
- Home Return Mode: Automatic homing using ORG, SD, and EL signals.
- Synchronous Start: Multi‑axis coordinated start via external STA signal.

Use Cases and Applications
- Semiconductor and PCB manufacturing equipment
- CNC and precision machining systems
- Pick‑and‑place robotics
- Automated inspection and packaging lines
- Laboratory automation and positioning stages

Compatibility
- Operating Systems: Windows XP, 7, 8 (32‑bit)
- Programming Environments: VB, VC++, BCB, Delphi
- Software Utility: MotionCreatorPro2 for configuration and diagnostics
